N-(Phenoxyalkyl)amides as MT1 and MT2 ligands: Antioxidant properties and inhibition of Ca2+/CaM-dependent kinase II [PDF]

open access: yes, 2013
Recently a series of chiral N-(phenoxyalkyl)amides have been reported as potent MT(1) and MT(2) melatonergic ligands. Some of these compounds were selected and tested for their antioxidant properties by measuring their reducing effect against oxidation ...

Adipocytes cause leukemia cell resistance to daunorubicin via oxidative stress response. [PDF]

open access: yes, 2016
Adipocytes promote cancer progression and impair treatment, and have been shown to protect acute lymphoblastic leukemia (ALL) cells from chemotherapies. Here we investigate whether this protection is mediated by changes in oxidative stress.

Characterization of the Mel1c melatoninergic receptor in platypus (Ornithorhynchus anatinus). [PDF]

open access: yesPLoS ONE, 2018
Melatonin is a neurohormone produced in both animals and plants. It binds at least three G-protein-coupled receptors: MT1 and MT2, and Mel1cGPR. Mammalian GPR50 evolved from the reptilian/avian Mel1c and lost its capacity to bind melatonin in all the ...

Rat pial microvascular responses to melatonin during bilateral common carotid artery occlusion and reperfusion [PDF]

open access: yes, 2011
The present study assessed the in vivo rat pial microvascular responses induced by melatonin during brain hypoperfusion and reperfusion (RE) injury. Pial microcirculation of male Wistar rats was visualized by fluorescence microscopy through a closed ...

Melatonin inhibits granulocyte adhesion to ICAM via MT3/QR2 and MT2 receptors [PDF]

open access: yesInternational Immunology, 2015
AbstractNeutrophils are cells of the innate immune system that first respond and arrive to the site of infection. Melatonin modulates acute inflammatory responses by interfering with leukocyte recruitment. It is known that melatonin modulates granulocyte migration though the endothelial layer thereby acting on the endothelial cell. Here we investigated

Orphan GPR61, GPR62 and GPR135 receptors and the melatonin MT2 receptor reciprocally modulate their signaling functions

open access: yesScientific Reports, 2017
Understanding the function of orphan G protein-coupled receptors (GPCRs), whose cognate ligand is unknown, is of major importance as GPCRs are privileged drug targets for many diseases. Recent phylogenetic studies classified three orphan receptors, GPR61,

Melatonin Receptors Agonistic Activities of Phenols from Gastrodia elata

open access: yesNatural Products and Bioprospecting, 2019
Gastrodia elata is a famous traditional Chinese herb with medicinal and edible application. In this study, three new polybenzyls, gastropolybenzylols G-I (1–3) were isolated from the EtOAc extract of G. elata.

The role of melatonin in mood disorders [PDF]

open access: yes, 2015
Melatonin (N-acetyl-5-methoxytryptamine) has been discovered as a hormone secreted by the pineal gland, even though it is also synthetized in various other organs, tissues, and cells.

Melatonin Alleviates Acute Sleep Deprivation-Induced Memory Loss in Mice by Suppressing Hippocampal Ferroptosis

open access: yesFrontiers in Pharmacology, 2021
Objectives: Memory decline caused by insufficient sleep is a critical public health issues and currently lacks effective treatments. This study objective was to explore alleviative effect of melatonin on sleep deprivation (SD)-induced deficiencies in ...

The ubiquitin-specific protease 8 antagonizes melatonin-induced endocytic degradation of MT1 receptor to promote lung adenocarcinoma growth

open access: yesJournal of Advanced Research, 2022
Introduction: The human genome encodes two melatonin receptors (MT1 and MT2) that relay melatonin signals to cellular interior. Accumulating evidence has linked melatonin to multiple health benefits, among which its anticancer effects have become well ...
